Sienal is shifted, -a cell contammg gas 'under ressure andrneans connected with the cell or .automatically generating the gas; this means, in one' form, consists ofv a comparte ment containinghydrochloric' acid, a. com' pertinent containing vtinely dividedmarble, a passage-between these compartments and a gate orvalve controlled by the variation in the ressure, of the gas in the cell bv i which t e passage is opened and closed. VAter the gas vis generated it ispreferred i and connected kwith the signa that it be passed through some material, like bi-carbonate of sodalto remove any acid troni the gas. Themotor ma Ibe arranged 4 substantially as .shown and described in' Unit-'ed States Letters Patent No. '743975, dated November 10, 1903, issued upon my applicationexcept that in 'the arrangement herein shown and,

open-ing inthe cover 30 to a chamberf fixed upon the cover; Within 'the chamber f is a diaphragmd to which the rod 38is `firmly attached'; there isa helical spring g of considerable mechanical strength connected to the diaphragm d at one end and to anadj'us'ting screw 40 passing through the vwall of l i the chamber f at the other end. A thumb There 1s combined with the signal at each signalstation a gas motor bv which the screw 41 passes through the wall of the chamber f mlposition to engage the connection between the springg and thediaphragm d; the object being to firmly hold the rod and diaphragm in fixed position when` the apparatus is taken apartfor any reason, and to thus protect thediaphragm dD A end 1s connected with said rod by a section of rubber tubing 43 to form an expansion joint. There are a series of trays t pervious to gas .and preferably made of perforated hard rubber sheets with soft rubber gaskets 44. Within the cell 34 is a quantity of iinely divided marble or marble dust and Within'. each tray t is a4 layer or quantity of bi-carbonate of-soda 60. At the top of the receptacle there is a pipe p connecting the cell with the signal operating apparatus (see Fig. 2); in thisl pipe there is a valve 'v to be operated by hand and closed when it becomes' necessary to re lenish the gas producingmat'erial in the ce l e.

Q In Figs. 2 and 3, s is a semaphore signal ind'er c (see F1g.l2) a magnet m controls the passage for the gas from the cell e. lnFig.`3, there are two signal sections shown, a and b, with their 'signalsv s. The rails are separated -by insulating jointsi; at one end of each section there isfa'batterv 19 connected by conductors 20 and 21th the rails vin a well known manner.' At the opposite end of each section there is a magnet o connected in circuit with the conductors 22, 23, the rails of the sectionl andthe battery 19.- Each magnet o l pipes-2 surrounds the rod 3 8 and at itsupper y o crates anarinature 'bar 50 to open and c ose the local circuit 51 containin 'a battery 52 and the. electro-magnet Vm efore described. The arrangement of the track and signal circuit is well known. :When a train c `.enters the tracksectionl a, itl demagnetizes themagnet o, and the circuit 51 is broken. Magnet'm operates a valve in the pipe con necting tlievcell e with the cylinder c, alias shown and described in United States-Lets' ters 4Patent 743975, dated November 10, 1903,v except that in the present arrangement no 'reducing valve is employed-L. This admits gas to the cylinder which operates upon the piston toshift the signal n normally standing at danger. It is to be understood that'theie is a normal charge of gas in the cell e which exerts a pressure upon the diaphragm d and the diaphragm d operating throughthe rod 38 closes thedoor o rvalve 37 and thus preventsthefurther feeding of the finely dividedinarble from the lcell :34 to" the cell 32, andfwhen by the operation ofthe signal the gas pressure in the cell e is; reduced the valve d operating through the rod 38 opens the valve 37 to allow'.4 a further quan` A tity of marble dust topass through the aperture 36 `into the acid 33,V the' gas generated from this union of the. marble dust with the hydrochloric acid is the result of .a well.'V known process; the gas rising. through the marble dust and throughl the perforated trays tcontaining the bicarbonate of soda' 60 f rees itself from any trace of acid; the gas again exerts lpressureupon the diaphragm and the valve isl again closed. This opera-l tion isrepeated successively -until the acid producing substancesin the cell'are exhaust-4 ed. The quantity of acid. producing substance in the cell e should be-suflicient to operate the signal several thousand times. `Vl/'hat I claim and desire to secure by Letters Patent is:
